Hello!
I have a brick house of 200 sqm including the basement, built in 1970. The basement is mostly dry, but the room where the family room and the pantry are has too high moisture levels in the studs according to Anticimex (The pantry only has plaster and painted walls). My thought was to start by removing the family room, to eliminate the risk construction and then drain. The family room is traditional, with raised studs and insulation on the interior walls, and a floating wooden floor.
My plan is to use materials that withstand moisture in the family room, plastered walls and needle felt carpet or tiles, what do you think about that? Does plaster withstand moisture without coming off? I thought I would first refurbish the family room and if I still find that moisture is a problem, then redo the drainage. Does that sound like a reasonable plan?
Regarding drainage, I have 2 cast slabs around the house, 1 garage and a large patio, and a masonry/cast staircase down to the basement. I estimate that I can drain 2/3 of the house without having to break up the slabs. It's the part of the house with the family room that has had the most moisture penetration (For example, in the pantry, the paint has come off, but it seems to be a dense plastic paint), that part of the house is very easy to drain.
Is it possible to drain just a part of the house?
